[0028]FIG. 2 shows a system configuration of the elevator system 1000
according to the first embodiment. In FIG. 2, car control devices 200A
and 200B for respectively controlling cars 250A and 250B and the
elevator-hall-call/destination-floor-call registration devices 100A and
100B (a call receiving device) provided at the elevator hall are
connected via the network 700 to the group management control device 300.
Here, FIG. 2 shows two car control devices and two
elevator-hall-call/destination-floor-call registration devices, which is
shown as an example. The elevator-hall-call/destination-floor-call
registration device and the car control device, etc. can be plural such
as two or more.

[0029]In the elevator system 1000 according to the first embodiment, the
elevator-hall-call/destination-floor-call registration device which is
provided at the elevator hall includes a disabled person button 102 for
declaring to be a disabled person besides a destination floor
registration button 101 such as numeric keypad, etc. configured by
buttons having respective numbers of 0 to 9 for registering the
destination floor. Then, the group management control device 300 for
managing plural cars is configured to issue a lighting instruction of
hall lantern or a ringing instruction of chime corresponding to each car
only when the disabled person button 102 is pressed (only when the
declaration of being the disabled person is made).

[0030](Car Control Device 200A)

[0031]Car control devices 200A and 200B are provided for the cars 250A and
250B, respectively, connected to hall lanterns 400A and 400B (an example
of a lighting device) or chimes 500A and 500B (an example of a sound
generating device) corresponding to the respective cars 250A and 250B,
and control respective connected equipments under control of the group
management control device 300. The hall lantern or the chime is an
example of a notifying device to notify the disabled person of the car to
ride on. As shown in FIG. 2, at the elevator hall which is provided with
the elevator-hall-call/destination-floor-call registration devices 100A
and 100B, the hall lantern and the chime corresponding to respective cars
are provided around doors of the cars at the elevator hall side. Further,
car number display plates 260A and 260B showing car numbers are provided.

[0033]In FIG. 3, (a) shows an outer appearance of the
elevator-hall-call/destination-floor-call registration device 100A, which
is an enlarged view of the elevator-hall-call/destination-floor-call
registration device 100A of FIG. 2. In FIG. 3, (b) is a block diagram
showing main configurational elements of the
elevator-hall-call/destination-floor-call registration device 100A. The
elevator-hall-call/destination-floor-call registration device 100B has
the same configuration with the elevator-hall-call/destination-floor-call
registration device 100A. As shown in (a) of FIG. 3, the
elevator-hall-call/destination-floor-call registration device 100A (also
called as an elevator hall operation board) includes the destination
floor registration button 101 such as numeric keypad, etc. configured by
buttons having respective numbers of 0 to 9 as an elevator hall inputting
means by which the destination floor call can be registered at the
elevator hall, a disabled person button 102 for declaring a customer to
be a disabled person, and a display unit 103 which is, for example, a
liquid crystal display unit showing the inputted destination floor and
the number of the assigned car. The
elevator-hall-call/destination-floor-call registration device 100A sends
information of the destination floor inputted by the destination floor
registration button 101 and information showing the presence or absence
of press of the disabled person button 102 to the group management
control device 300. The group management control device 300 determines
assignment of cars based on the above information sent from the
elevator-hall-call/destination-floor-call registration device 100A and
sends the car assignment information to the
elevator-hall-call/destination-floor-call registration device 100A.

[0036]As shown in FIG. 2, the group management control device 300 includes
a call detecting unit 310 (the inputting unit) having a disabled person
detecting unit 311, and a call registering unit 320 having an
assignment-evaluated-value computing unit 321 and a car assignment
determining unit 322. The call detecting unit 310 detects a call from the
elevator-hall-call/destination-floor-call registration device 100A or the
elevator-hall-call/destination-floor-call registration device 100B. At
this time, the disabled person detecting unit 311, when the call (the
destination floor call) is detected, detects whether the disabled person
button 102 is pressed or not. The call detecting unit 310 outputs the
detected call, and when "the disabled person button 102 is pressed" is
detected by the disabled person detecting unit 311, information showing
"the disabled person button 102 is pressed" to the
assignment-evaluated-value computing unit 321.

[0037]The assignment-evaluated-value computing unit 321 computes an
evaluated value of all cars 250A and 250B which are cars to be assigned
for calls inputted by the call detecting unit 310. The
assignment-evaluated-value computing unit 321 outputs the evaluated value
of the car 250A and the car 250B obtained by the result of computation to
the car assignment determining unit 322. The computation of the evaluated
value belongs to the conventional technique.

[0038]The car assignment determining unit 322 compares respective
evaluated values of the cars 250A and 250B inputted from the
assignment-evaluated-value computing unit 321 and determines the optimal
car. The car assignment determining unit 322 sends a car responding
instruction to make the car to be assigned respond and, when "the
disabled person button 102 is pressed" is detected, a signal to instruct
lighting the hall lantern and a signal to instruct ringing the chime to
the car control device 200A or the car control device 200B corresponding
to the determined assigned car. The car assignment determining unit 322
sends an assigned-car-number displaying instruction to display the
assigned car number to the elevator-hall-call/destination-floor-call
registration device 100A (or the
elevator-hall-call/destination-floor-call registration device 100B) at
which the destination floor is inputted. On receiving the
assigned-car-number displaying instruction, the
elevator-hall-call/destination-floor-call registration device displays
the assigned car number on the display unit 103.

[0039](Explanation of the Operation)

[0040]FIG. 4 is a flowchart showing a processing flow of the elevator
system 1000. The operation will be explained according to the flowchart
of FIG. 4. In the following explanation of the operation, although the
explanation will be done using a case in which the
elevator-hall-call/destination-floor-call registration device 100A is
operated, the operation is the same when the
elevator-hall-call/destination-floor-call registration device 100B is
operated. In the following explanation, it is assumed that the
destination floor call is inputted from the
elevator-hall-call/destination-floor-call registration device 100A, and
the group management control device 300 determines to assign "the car
250B" for this input.

[0044]The disabled-person-declaration receiving unit 120 inputs the
destination floor, and at the same time detects the presence or absence
of pressing the disabled person button 102 (S3), and outputs the detected
result as "information showing the presence or absence of pressing the
disabled person button 102" (disabled person information, hereinafter).
When the disabled person button 102 is pressed, the
disabled-person-declaration receiving unit 120 detects "the disabled
person button 102 is pressed", and outputs "information showing that the
disabled person button 102 is pressed" (an example of a disabled person
signal) as the disabled person information. The communication unit 140
transmits "destination-floor-call information" and the "disabled person
information" to the group management control device 300 via the network
700.

[0045](Group Management Control Device 300)

[0046]The call detecting unit 310 receives the "destination-floor-call
information" and the "disabled person information" via the network 700.
The call detecting unit 310 detects a destination floor call from the
received "destination-floor-call information". Further, the disabled
person detecting unit 311 detects presence or absence of pressing the
disabled person button 102 from the received "disabled person
information". When "the disabled person button 102 is pressed" is
detected together with the detected call (the destination floor call) by
the disabled person detecting unit 311, the call detecting unit 310
outputs information of "the disabled person button 102 is pressed" to the
assignment-evaluated-value computing unit 321. The
assignment-evaluated-value computing unit 321 registers the destination
floor call, and for all the cars 250A and 250B which are cars to be
assigned, computes evaluated values for the call inputted by the call
detecting unit 310. The assignment-evaluated-value computing unit 321
outputs the evaluated values of the car 250A and the car 250B obtained by
the computed result to the car assignment determining unit 322.

[0047]The car assignment determining unit 322 selects the optimal car out
of the managed cars based on the evaluated values. At this time, when
cars for the disabled person's use are separated from cars for the
able-bodied person among the cars, the car assignment determining unit
322 selects the optimal car from the cars for the disabled person's use
(S4). Namely, when the destination floor receiving unit 110 receives the
destination floor call, and if the disabled person signal is outputted
from the disabled-person-declaration receiving unit 120, the car
assignment determining unit 322 determines an elevator car to be assigned
for the registered destination floor call from at least one elevator car
for the disabled person's use which has been preset for the disabled
person's use. In this example, it is assumed that the car assignment
determining unit 322 determines the car 250B.

[0048]The car assignment determining unit 322 sends the number 250B of the
determined assigned car to the elevator-hall-call/destination-floor-call
registration device 100A to which the destination floor call is inputted.

[0049]The communication unit 140 of the
elevator-hall-call/destination-floor-call registration device 100A
receives the number 250B of the car. The display circuit unit 130
displays the number 250B of the car (the assigned car) received by the
communication unit 140 on the display unit 103 (S5).

[0050]Further, the car assignment determining unit 322 sends a hall
lantern lighting instruction to instruct to turn on the hall lantern 400B
and a chime ringing instruction to instruct to ring the chime 500B to the
car control device 200B which controls the determined assigned car 250B.
The car control device 200B turns on the hall lantern 400B corresponding
to the car 250B and as well rings the chime 500B corresponding to the car
250B (S6). The car assignment determining unit 322 sends additionally a
"car responding instruction" to the car control device 200B to make the
car 250B respond to the floor at which the destination floor call is
registered (S7).

[0051]The car assignment determining unit 322, when the pressing of the
disabled person button 102 is not detected by the disabled person
detecting unit 311 at the time of inputting the destination floor call,
promptly selects (determines) the optimal car out of the managed cars
(S8), and sends the number of the determined assigned car to the
elevator-hall-call/destination-floor-call registration device 100A to
which the destination floor call is inputted. Also in this case, it is
assumed that the car assignment determining unit 322 determines the car
250B.

[0052]The communication unit 140 of the
elevator-hall-call/destination-floor-call registration device 100A
receives the number 250B of the car. The display circuit unit 130
displays the number 250B of the car received by the communication unit
140 on the display unit 103 (S9).

[0053]The car assignment determining unit 322, when the disabled person
information of "the disabled person button 102 is pressed" is not
inputted from the call detecting unit 310, does not send the hall lantern
lighting instruction nor the chime ringing instruction to the car control
device 200B which controls the assigned car 250B but sends only the "car
responding instruction", and makes the car 250B respond to the floor to
which the destination floor call is registered (S10).

[0054]In the examples of FIGS. 2 and 4, when the disabled person button
102 is pressed at the time of inputting the destination floor, the hall
lantern corresponding to the assigned car is turned on, and the chime
corresponding to the assigned car is rung. However, either of the hall
lantern and the chime can be operated. Namely, the following is the case.

[0055](In Case of Ringing the Chime)

[0056]A case will be explained in which only the chime sound is generated.
The elevator system includes the chime as the notifying device, and the
hall lantern is not necessarily provided. In this case, the disabled
person button 102 is provided for the visually impaired person's use. At
the time of inputting the destination floor, when the disabled person
button 102 for the visually impaired person's use is pressed, only the
chime is operated. The contents of the operation are the same as the one
of FIG. 4.

[0057](In Case of Lighting the Hall Lantern)

[0058]A case will be explained in which only the hall lantern is lit. The
elevator system includes the hall lantern as the notifying device, and
the chime is not necessarily provided. In this case, the disabled person
button 102 is provided for the hearing impaired person's use. At the time
of inputting the destination floor, when the disabled person button 102
of the hearing impaired person's use is pressed, only the hall lantern is
operated. Here, the notifying device for notifying the hearing impaired
person is not limited to the hall lantern, but it can be a display device
(a liquid crystal display, for example) provided corresponding to the car
for displaying predetermined information as a notice. For example, if the
third floor is inputted as the destination floor, the display device
shows the display such as "the car for the third floor is arriving" as
the predetermined information.

[0059]FIG. 5 is a flowchart showing a case in which announcement is done
for the visually impaired person. The respective car control devices
include speakers 600A and 600B for announcement as shown in FIG. 2.
Further, the elevator-hall-cal/destination-floor-call registration device
100A includes a speaker 104 for announcement. To facilitate the use by
the visually impaired person, when the disabled person button 102 is
pressed (S11), the display circuit unit 130 displays the destination
floor inputted by the destination floor registration button 101, and at
the same time makes announcement of the inputted destination floor via
the speaker 104 (S12). Further, when the car assignment determining unit
322 determines the assigned car (S13), the car assignment determining
unit 322 displays the assigned car number on the display unit 103 via the
display circuit unit 130, and at the same time makes announcement of the
assigned car number via the speaker 600B (when the car 250B is determined
to be assigned) (S14), and in addition, turns on the hall lantern and
rings the chime of the corresponding car (S15). Here, the car assignment
determining unit 322, when the car which responds (S16) arrives at the
elevator hall, can make announcement of the number of the corresponding
car via the speaker 600B (S17).

[0060]By the elevator system 1000 according to the first embodiment, when
the disabled person makes a call, the hall lantern of the car to ride is
turned on, and the chime of the car to ride is rung. Because of this, the
disabled person can easily find the car to ride and can move to the car
to ride smoothly. The elevator system 1000 turns on the hall lantern only
when the disabled person button 102 is pressed, so that electrical
capacity for lighting the hall lantern can be saved.

[0061]In the foregoing embodiment, the elevator system has been explained,
in which

[0063]the group management control device calculating the evaluated value
of each car and selecting the optimal car to be assigned;

[0064]the car control device controlling each car;

[0065]the chime corresponding to each car; and

[0066]the hall lantern corresponding to each car are included, and

[0067]when the disabled person button of the
elevator-hall-call/destination-floor-call registration device is pressed
and as well the destination floor call is registered, of the assigned
car, the chime is rung and further the hall lantern is turned on.

[0068]In the foregoing embodiment, the elevator system has been explained,
